Wanganui, New Zealand Application May 27, 1932, Serial-No. 613,995 In New Zealand April 22, 1932 2 Claims.

This invention relates to containers for powdered and granular substances, provided with means for enabling a predetermined amount of the contained substance to be delivered from 5 the container upon the latter being tipped or tilted to a required angle.

The object of the present invention is to provide a container of the class above referred to with an improved form of substance measuring device, capable of being readily fitted to existing containers, or to containers during the manufacture thereof, at small cost, in order that accurate predetermined amounts of substances placed within the containers, may be obtained at will in a simple manner, the measuring device being formed and fitted in such a way that the containers are capable of being closed to atmosphere to preserve their contents, if desired. I

The invention consists in forming a container for powdered and granular material with a discharge passage which extends from the bottom of the container and opens through the upper portion thereof, said passage communicating through a measuring opening adjacent its lower end, with the interior of the container:

The invention is illustrated in the accompanying drawing, wherein it is shown applied in different ways to containers,

Fig. 1 being a sectional elevation of a container provided with a vertical discharge passage opening through the top of the container,

Fig. 2 a sectional elevation of a container having an inclined discharge passage which passes through the top of the container to serve as a spout,

Fig. 3 a sectional elevation of a container provided with an inclined discharge passage opening through and removable with the lid of the container, and

Fig. 4 a sectional elevation of a container wherein the discharge passage opens through a side thereof and is extended for use as a spout.

In its simplest form, the discharge passage is provided by a tube 1 placed vertically in the container 2 and secured to the inside thereof so as to extend from the bottom of the container and open through the top 3 thereof.

An opening 4 in the side of the tube 1 adjacent the lower end thereof provides the means of communication between the interior of the container 2 and the tube 1.

The top 3 of the container is preferably re- 55.movable in order to enable the latter to be refilled as required, while the upper end of the tube 1 can extend into a ring 5 of suitable height secured on the top 3, and which is capable of being closed by a cap 6 or other closure in order to prevent air reaching the contents of the container. From the foregoing it can be seen that the ring 5 serves to fix the tube 1 in position and prevent accidental displacement thereof. Also when the top 3 is removed the tube 1 can be easily disengaged from the ring 5 and all the parts of the container can be thoroughly cleaned thereby.

The height of the opening 4 from the bottom of the container 2 and the size of said opening, determine the amount of the substance which enters the tube 1 and is delivered therefrom at a single operation, the substance entering the tube 1, through the opening 4 to a level coinciding with the highest point thereof, as indicated upon the drawing, and upon the container being tipped in the direction indicated by the arrows, only the substance already in the tube 1 is discharged through the outer end of the tube which has been opened for the purpose, the remainder of the contents of the container falling away from the opening 4 and so being retained in the container.

Thus, by the simple operation of tipping the container to discharge therefrom the substance already in the tube 1 and measured by the opening 4, a predetermined amount of the contents of the container can be obtained as required.

To repeat the measured amount, the container is returned to its normal or vertical position, to allow the tube 1 to refill to the level of the highest point of the opening 4, following which the container is again tipped to discharge the measured amount from the tube 1.

In order to facilitate the pouring or discharge of the substance in the tube 1 from the latter, said tube can be fitted obliquely or inclined at a suitable angle in the container and be extended either through the top thereof or through the upper portion of the container side, in the form of a spout, although it is not always necessary or desirable to have the tube 1 projecting from the container.

The opening 4 which measures the amount of the containers contents to be discharged at a single operation or throw of the container, must of necessity be formed in the wall of the discharge passage farthest removed from the container side the upper portion of which is lowered when the container is tipped.

In the form shown in Fig. 3, the tube 1 can be attached to and be removable with the top of the container.

As in the form of device illustrated in Fig. 1, the tubes 1 in the remaining figures of the drawing can be closed by any suitable form of closure if desired.

Although the tube 1 is illustrated and described as providing the discharge passage, the latter need not necessarily be contained in a tube, as said passage can be formed in other Ways without departing from the principle of the invention.

What I do claim and desire to obtain by Letters Patent of the United States of America is:-

1. Means for holding and measuring small quantities of powdered dry material comprising a vessel, a cover for the vessel, provided with a hole, a cylindrical tube removably arranged in the vessel and extending from the bottom of the vessel and projecting through the hole in the cover said tube being provided with an emission opening at its lower end for measuring definite quantities of material to be poured, means secured to said cover adjacent to said hole for anchoring the tube and preventing displacement thereof and a cap removably engaged with said means for closing the tube.

2. An arrangement as claimed in claim 1, wherein the means for preventing displacement of the tube includes a ring fixed on the cover about the opening and having an inwardly turned outer portion for embracing the outer edge of the tube.
